My board included Artist's Talent (at 3rd Chapter), and Ojer, both of which should have increased my Lightning Helix damage, which targeted the opponent. All I got as a 3 damage. I suspect the interplay of Ojer and the Talent prevented this from going up (Ojer should have increased it to 4 (that was his stat) and Talent should have increased to 5 (3 + 2). Even if it only did just one of them the damage should have increased.
